To all whom it may concern: 7

Be it known that I, ROBERT W. BARKER, a citizen of theUnited States,residing in Pat- .erson, Passaic county, New J erse ,have invented acertain new and usefu Im rovement in Winding-Machines; andI do ierebydeclare the followin to be a full, clear, and exact description 0 theinvention, such as willenable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

My invention relates to machines for wind ing thread or yarn from swiftsonto bobbins or the like. The common practice in these machines is torotate the bobbin or other thread or yarnreceiving device and utilizethe pull emanatin therefrom to effect the rotation of the swi t or othersupply medium necessary to produce the unwinding ofthe thread from thelatter. High speed, accompanied by a uniform winding of the thread oryarn on the receiving de'vlce and with as infrequent breaking of thethread or yarn as 1 is possible, is a desideratum in the use 'of amachine of this character, but heretofore it was impossible to increasethe speed beyond a certain limit owing to the inertia of the supplymedium, which, because it was the cause of the swift running constantlyunder a condition of varying speed, produced either so frequent breakingof the thread or a failure of uniform winding thereof that any gainaccom lished by increase of speed was directly 0 set by a correspondingloss either in an inferior product or in loss of time spent in repairingbroken threads.

My principal object is so to construct a winding machine of thecharacter above indicated that the speed may be materially increased andyet a uniform tension maintained on the thread or yarn, with theconsequence that the winding is kept uniform and breakage of the threador yarn is not increased.

In an application for U. S. Letters Patent for winding machine alreadyfiled by me, Serial No. 517438, the thread, while being drawn lengthwiseb the winding means, was caused to exten around the periphery of amember having a continuous portion whose axis was substantiallycoincident with that of the swift, said member being prefer ably rotatedin the direction of unwinding the thread from the swift. In. the presentinvention, I providea" guiding member havin a substantially circularguiding portion w ich preferably surrounds the swift and has its axiscoinciding with that of the swift and atraveler arranged to. move onsaid guiding portion, said member being preferably rotated in thedirection of unwlnding the thread from the swift.

briefly outlined.

Another art consists in an improved construction o ring and traveler'tobe employed 6 One part of my present invention is thus particularl inwinding the thread on the 10 receiving evice.

My invention further consists in a novel construction and arrangement ofa spindle for carrying the thread-receivin device and a flier carrying asleeve throug which the spindle extends.

In the accompanying drawings, Fi re 1 is I a view in front elevation ofthe rig t-hand end of so much of the improved winding machine as it isnecessary to show for the purpose of illustrating the invention; Fig. 2is a verticalsectional view taken in a plane between the two windingunits shown 1n Fig. 1 and looking toward the right in said figure; Figs.3 and 4 are details illustrating the improved ring and traveler employedin connection with the thread receiving device; and, Fig. 5 illustratesa detail affecting parts A' and B, i

In the drawings, a .designates a suitable frame comprising an upper railb and 'a lower rail 0. The upper rail 22 carries a series of arms at inwhich are supported the swifts A and the rotary members and travelers Bwhereby the thread is unwound from the Swifts; in the lower rail 0 isarranged the means C, for effecting the winding of the threads. v

The parts B and C will now be described i detail, as also the meanswhereby they are supported and otherwise arranged and coordinated so asto cooperate with each other.

Referring, first, to the swift'A: the swift is of usual construction andhas its hub e journaled on a sleeve 1 which itself is 'journaled on ahorizontal shaft 9 projecting from the arm d, the sleeve being retainedon the shaft by a collar h pinned to the latter and the hub of the swiftbeing interposed f, z' and 7' form the axial portion of this memher;from the hub i pr o ect the radial arms is which at their outer endscarry a ring Z which is concentric with the sleeve f, and

from this ring project, parallel with the axis of member 6, arms 12?.whose free ends are turned in radially. To the free ends of the arms mis attached a ring 12 which is flat in cross-section, the said ends ofthe arms being secured to the ring a midway between i its lateral edges(see Fig. 1) so as to leave said edges continuously free or clear. Onthis ring n is loosely arranged a C-shaped or other suitableform oftraveler p, the same being adapted to run freely around the -ring.

Referring now to the winding means C. ()n the rail 0 is arranged aforked bracket q in which is journaled a vertical sleeve r having fixedthereto a pulley a which, beinn disposed in the forked portion of thebracket 9,

confines the sleeve against vertical movement. The sleeve is penetratedby a spindle t which is suitably secured at its iower end to a rockingbar a journaled in one of two 3 or more levers '0 (only one of which isshown) fulcrumed in the frame. This spindle carries at its upper end thespool w or other thread receiving member. In the present adaptation, thespindle reciprocates while the sleeve rotates, and in order to keep thespindle true in its reciprocations, without binding in the sleeve, thebore of the sleeve has only a limited portion 00 thereof, preferably atits lower end, fitting the spindle, the remaining portion g of said borebeing of slightlv larger diameter than the spindle. The sleeve 1" formsthe lower part of a flier, the upper partof which consists of a-,.fork 2the upper ends of whose arms carry a ring 1 which is T-sha ed incrosssection (see Figs. 4 and 5) so t at the inner and outer continuousflanges 2 and 3 are formed at the top thereof, the same standing clearof the upper ends of said arms.

' On the flanged portion of the ring is ar ranged a C-shaped traveler 4.In the ring and bearing upwardly toward its inner flange 2 and againstthe traveler 4 is a ring 5 engaged from beneath by a light spiral 5spring 6 which is su ported at one point bv having one end 7 introducedinto the ring and at the diametrically opposite point by a pin 8 in thering.

9 is a rotary shaft journaled in the frame and driven in any suitablemanner. On

this shaft is arranged a pulley 10 around which and the pulley j extendsa belt 11. On said shaft is-also arranged a pulley 12 around which andthe pulleys extends a 5 belt 13. In one side of the frame is journaled acounter-shaft 14 carrying a heartcam 15 en aged by a roller 16 on the uper end of a pit-man 17 guided for vertical movement in the frame andconnected at its lower end to the lever '0. Rotary motion is transmittedto the shaft 14 from shaft 9 by the gearings 18, 19 and 20. The threadextends from the skein D through the traveler a, then around aperipheral ring 21 surrounding and carried by the right-hand spokes inFig. 1 of the swift A, then through a thread guide 22 carried by theframe or by the adjoining arm ain the axis of the guiding member B andswift, then over a bar 23, and then through the traveler 4 to the spoolor bobbin-w. The swift does not normally rotate, it being held againstrotation by the weights 24 carried by two of its spokes. The shaft 9being driven, it causes the rotation of the flier-carrying sleeve 1",the vertical reciprocation of the spool and the rotation of the memberB, the spool rotating in the direction to wind the thread thereon andthe member B rotating in the direction of unwinding the thread from theswift. (If the skein should be placed on the swift so as to require itto be unwound in the direction reverse to that indicated in Fig. 1, themember B should be rotated in the reverse direction and this may beaccomplished by crossing the belt 11.) The tendency of the traveler 72under the pull of thethread is, to

advance around the ring n inthe direction of unwinding, and thistendency is assisted by the rotating ring a. If the thread should catchin the skein, the ring impels the traveler and tends to cause it todisengage the thread at the point where it is caught, an effect whichobviously would not be produced as efliciently if the ring werestationary. As the flier carried by the sleeve 1" is rotated, it carriesthe traveler 4- around with it and thus lays the thread in coils on thespool while the spindle is reciprocating the bobbin and producin thenecessary traverse. The traveler 4 being free to move around the ring 1,it affords the necessary yield to the thread should the speed of thespool become unduly high. It will be understood that the spring-actuatedring 5 serves to keep the traveler 4 normally rotating with the ring,while allowing it sufficient lost motion with respect thereto in the wayabove indicated should occasion require.
